The cone A has the length of the lateral side = h and the height of the cylinder B = h.
Since, the lateral surface areas are given by,
Lateral surface area of cone =
, where l is the length of the lateral side.
So, we get
=
.
Also, Lateral surface area of cylinder is
, where h is the height of the cylinder.
So, we get
= 
Thus, we see that, 
Hence, the given statement is correct.
